BRACKET FOR PENDENT ELECTRIC-LIGHT GLOBES.

SPECIFICATION forming part of Letters Patent No. 570,452, dated November3, 1896.

Application filed January 5, 1895- To ctZZ whom it may concern:

Be it known that we, JOHN CHRISTIANSEN and REINHART W. PITTMIAN,citizens of the United States, residing in Hartford, in the county ofHartford and State of Connecticut, have invented a new and usefulBracket for Pendent Electric-Light Globes, of which the following is aspecification.

This invention relates to lamp brackets or supports, and is moreespecially designated as a gravity-support, and is more particularlyadapted for suspending or supporting incandescent electric lamps and theobject of the invention is to provide a supporting or suspension devicesimple and durable in construction, neat in appearance, and simple inoperation, and by meansof which the lamp can be adjusted into anydesired position within certain determinate limits.

A further object of the invention is to provide a bracket of this classadapted to be suspended from a ceiling or other place whereby the lampcan be adjusted into any desired lateral position relatively to itssupporting or suspension means without changing the position of suchsupporting means, and whereby it can also be adjusted in a circularhorizontal path relatively to its supporting means without twisting orturning such supporting means.

In the drawings accompanying and forming part of this specification,Figure 1 is a side elevation of this improved bracket suspended from aceiling and showing the lamp-supporting member or rod adjusted to itsextreme extended position relatively to the weight and showing theweight adjusted in position to equalize the weight of and maintain thelamp in proper horizontal position, and also showing such weight partlyin section. Fig. 2 is a similar view to Fig. 1, but showing the weightsupported by an incandescent-lamp cord,the lamp-supporting member or rodcarried by a sleeve secured to the weight, and also showing saidlamp-supporting member in a different position from that shown in Fig. 1and the weight adjusted to equalize the position of the lamp. Fig. 3 isa transverse sectional view of the weight, taken in line a a, Fig. 1.Fig. 4 is a side view of the coupling detached. Fig. 5 is a view SerialNo. 533,972. (No model.)

descent-light cord and the lamp-supporting member in a differentposition from that shown in Fig. 6. Fig. 8 is an enlarged view of thecoupling shown in Figs. 6 and 7 3; and Fig. 9 is a transverse sectionalview thereof, taken in line b b, Fig. 8.

Similar characters of reference indicate corresponding parts in thedifferent figures.

By means of this gravity suspension-bracket anincandescent-electric-light lamp or other lamp can be suspended from aceiling or wall or other suitable place by a perpendicular or pend uloussuspension or supporting member, and adjusted and held in any desiredlateral position relatively to said suspension mem ber by means of asuspended weight, and also adjusted in a circular horizontal pathwithout turning or changing the position of such suspension member.

In the preferred form thereof herein shown and described this improvedlamp-bracket comprises a suitable pendulous suspension or supportingmember preferably consisting of a wire or cord 12, of any desiredthickness or shape, adapted for attachment by any suitable means to anysuitable support, such, for instance, as a ceiling of a room or otherplace, but in practice this suspension member is preferably aboutone-eighth of an. inch in diameter, and is preferably flexible, wherebyit can be easily moved aboutif desired, but, although preferablyflexible, the lamp can be turned in a circular horizontal direction, bymeans of the coupling hereinafter set forth, without twisting or turningthe suspension member or wire, so that the lamp carried by the bracketwill remain in its adjusted position without any vibrating or swingingmotion. This suspension member 12 may consist either of theincandescent-light cord or wire (see Figs. 2 and 7) or of a separatecord or wire, (see Figs. 1 and 6,) as desired.

Secured to the lower end of the suspension member or -wire 12, by anysuitable means, such as by a coupling, is a weight 13, pref crablyconstructed to exceed the weight of the lamp or globe when the same isattached to the bracket, whereby the lamp can be adj usted into positionat a relatively remote distance therefrom and the weight of the lampequalized and by slight adjustments of the weight permit the lamp to beadjusted into various positions transversely of said weight and thesuspension member. This weight, which may be of any desired shape orform, in its preferred form herein shown and described is preferablylongitudinally and centrally bored, (Figs. 1 and 6,) whereby it isadapted to receive a lamp-holding member of any desired construction,and herein shown preferably consisting of a rod 14, which islongitudinally adjustable relatively to said weight and alsotransversely thereof and of the suspension member 12. This lamp-holdingmember may be clamped in its adjusted position by means of a suitableclamping device, such as a thumb-screw 15, carried by the weight, and ispreferably provided at or near one end thereof with suitable means forsupporting amincandescent electric lamp, or other lamp, and which meansis herein shown consisting of spring clamping-arms 35, adapted to springaround the metal holder of an incandescent-electric-light lamp when thisparticular form of light device is used with this bracket.

In one form of this improved lam p-support-' ing bracket the weight haspivotally secured thereto an arm 16, and as one means of securing thisarm in position relatively to the weight said arm is shown provided witha bifurcated end 17, adapted to receive an ear or projection 18,preferably carried by the main part of the weight, and to which the armis pivotally secured by means of a suitable clamping device, such as athumb-screw 19, extending through the bifurcated end 17 of the arm andthe ear or projection 18 of the weight. It will be obvious that toconstruet the weight with a bifurcated extension adapted to receive thearm is clearly within the scope of our invention.

Any suitable means for adjustably securin g the suspension member 12 andthe weight 13 in operative position relative to each other may be used,but in the preferred form thereof herein shown and described, however, acoupling is provided, and which in its preferred form comprises a hook20, adapted to receive the lower end of the suspension member 12, whichmay be secured thereto in any suitable way, and a swivel member or link21, secured to said hook in any suitable way, and which is herein shownhaving its lower portion forming a pivot or journal 22, adapted toreceive the upper end of the arm 16, which may be secured thereto in anysuitable way for adjustment, but in the form shown the arm terminates ina hook 23, adapted to extend around said journal.

In the use of this described form ,of bracket, the same having beenassembled and secured by means of the suspension member to a coiling ofa room or any other suitable place, preferably adjacent to the point ofattachment of the conductor-cord of the electriclight lamp, if aseparate suspension member is used, the lamp is then placed in positionin the holding member and said holding member adjusted into any desiredposition transversely of the weight and suspension member and secured insuch position by means of the clamping device 15. The clamping device 19is then actuated to permit the weight to be adjusted relatively to thearm into the necessary position to counterbalance or equalize the weightof the lamp, and said weight is then clamped in its adjusted position bymeans of said clamping device. For instance, with the form of lampshown, (see Fig. 1,) if a shade was added to the lamp, (see dottedlines,) it would be necessary, in order to have the weight equalize thisadditional weight of the lamp and shade, to adjust said weightrelatively to the arm 16 laterally of the suspension member or fartherto the right, and thus by the adjustment of the weight relatively to thesuspension member increase its amount of supporting power, an d wherebythe lamp would be brought into a horizontal position. If, however, thelamp was moved toward its suspension member the distance shown, forinstance, in Fig. 2, it would be necessary to adjust the weight to bringthe same toward the suspension member, to thereby decrease thesupporting power of the weight. The lamp can then be turned by means ofthe swivel into any desired circular horizontal position withouttwisting or turning the suspension member out of its normal position.

lVhen it is desired to adjust the lamp laterally of the weight into anydesired position, the lamp-holdin g member 14:is adjusted transverselyof the weight and clamped in such position by the thumb-screw 15, andthe weight adjusted by means of its arm 16 and clamping-screw 15 to theposition necessary to counterbalance or equalize the weight of the lampin its adjusted position.

According to another form of this improved lamp-bracket the pendulous orhanging suspension member and holding member are the same, but theweight 13 is preferably provided with an arm 25, integrally connectedtherewith, and which preferably extends sidewise or laterallythereof andis provided with suitable means whereby said weight can be adjustedlaterally of the suspension member. This means in its preferred formcomprises a laterally-extending arm orbar 26, having any desired numberof perforations 27 for the purpose hereinafter set forth. This bar issecured to the upper portion of the arm 25 by means of a swivel of anysuitable and desired construct-ion. In the form thereof shown the bar 26has a suitable base 28, through which a fastening device, such as ascrew 29, is adapted to extend and project into the upper end of the arm25, thereby forming a swivel connection whereby the weight can turn in acircular horizontal direction relatively to the bar. In thisconstruction the weight is secured by means of the bar 26 to thesuspension member, preferably by means of a suitable coupling preferablyin the nature of a double hook. 30 of any desired construction.

In the use of thisform of bracket the holding member carrying the lampis adjusted into any desired longitudinal position relatively to andtransversely of the weight, and secured in such position by means of theclamping device 15. The weight is then adj usted by means of itsperforated arm or bar 26 by placing the hook 30 in the particularperforation which will enable the weight to equalize the Weight of thelamp and properly horizontally balance the same. For instance, if thelamp-holding member is in its extreme extended position (see Fig. 6) thehook will be placed in the perforation c at the extreme inner end of thebar, but if such hook was left in one of the intermediate perforations,as d,the lamp and holding member would assume the position shown indotted lines. If the holding member, however, is moved transversely ofthe weight, (see Fig. 7,) to thereby adjust the lamp, the hook will beplaced in one of the intermediate perforations, as 6, whereby the weightwill be in position to properly equalize the weight of the lamp in itsadjusted position. By means of this construction of gravity-bracket thelamp will always be held in perfectly horizontal position and can beadjusted into any desired transverse position relatively to thesuspension member in proportion to the length of the rod, and alsoadjusted into any desired circular horizontal position relatively to thesuspension member as a center and remain in such position withouttwisting or changing the position of said suspension member.

In the construction shown in Figs. 6 to 9, however, when it is desiredto turn the lamp in a circular horizontal direction from one position toanother the perforated bar is released from the hook and the bar and theweight turned together and the hook replaced in the perforation, theswivel in this construction being used to permit the lamp to be adjustedinto position somewhat sidewise of the perfo rated bar and thesuspension member without the weight losing its counterbalancing forcerelatively to the lamp. By means of this construction of bracketembodying the laterally movable weight relatively to the pendulous orhanging suspension member the holding member can be supported inperfectly horizontal position with the weight at onelend and the lamp atthe other end thereof, or adjusted into any desired positiontransversely of the weight and the holding member, without the use ofany means of support secured to said holding member intermediate of saidweight and the lamp, and whereby different sizes and weights of lampscan be more readily and easily supported and adjusted into variouspositions than could be the case if the weight was secured in positionin alinement with the suspension member at all times.
